My wife had a windscreen replaced in her Audi a few years ago with third party glass. Similar sensation for me. I couldn't see any distortion, but I found myself constantly trying to refocus as I panned around the window. Especially in the curved edges. Made me dizzy! Had them replace it and it was fine. Deb didn't see it, so maybe something with her vision vs. mine. I get the same sensation when I use glasses with the astigmatism correction even a tiny bit off.
On a side note, the Japanese are extremely picky with their glass quality. When Honda built the plant here in Ohio, they sourced PPG molded glass. They were not happy with the quality no matter how much PPG tried. They ended up shipping duplicates of their glass molds from Japan to Ohio, and Japanese sourced plate glass. Then had several employees (including my Dad) spend six weeks in Japan learning how to mold glass properly. Even the tiniest flaw was scrapped. Maybe Toyota is similar in their QC at the plant in Japan.
